How to load JSON data in Cocos2d-X 3.0 in javascript

问题

How would one load a javascript structure (object or array) from a file in Cocos2d-X 3.

My res/test.json:

{
    version:"1.0",
    data:"this is some data."
}

I'm able to load the file content like so:

var data = fileUtil.getStringFromFile('res/test.json');
cc.log(data);

What is the best way to load the javascript structure from the string? Is there a function in cocos2d-x to do this directly?

回答1:

The "standard" JSON.parse works:

var fileUtil = cc.FileUtils.getInstance();
var data = fileUtil.getStringFromFile('res/test.json');
var jData = JSON.parse(data);

But note all attribute names must be passed in quotes, otherwise the parser will fail. res/test.json must then look like this:

{
    "version":"1.0",
    "data":"this is some data."
}
